IM PROVE'MENT IN WATER-M ETE RS.

Specification forming part of Leiters Patent No. 36.698, dated October 2l, 1862..

.To @ZZ whom it may concern:

Be it known that I, JOHN S. BAEDEN, a citizen of the United States of America, and a resident of the city and county of New Haven, and State of Connecticut, have invented a new and useful or Improved Water-Meter; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawings, of which- Figure lis a side elevation, and Fig. 2 a horizontal section, of it; Fig. 3,' a vertical and transverse section taken through the ed uctionpassage, the two valves, the cylinders, and pistons. Fig. tis a vertical and longitudinal section taken through one of the cylinders and one of the valves. Fig. 5 is a top view of the p bottom of the valve-case.

i In the said drawings, A. denotes the case of the apparatus, which, by means of one horizontal and two vertical partitions, a b c, is divided into a valve-chest, B, and four waterchambers, C C' D D. There is also an eduction pipe or passage, E, carried transversely through the ease and directly over two cylinders or` tubes, F F',which are arranged in the partition b, and respectively in the waterchambers (l C', as shown in the drawings. Each of the said cylinders F F' is open at its two ends and communicates freely with the two water-chambers next adjacent to its two ends-that is to say, the cylinder F opens into the chambers C D, while the cylinder F' opens into the chambers C' D'. Above the cylinders there are two chambered valves, G G', placed within the valve-chest B, one of them being directly over each cylinder. Underneath each valve there are three ports, d e f, made through the bottom of the valve-chest. Each port e opens into the eduction pipe or passage E. Furthermore, the ports f f open, respectively, into the water chambers D D', While the longest ports,d d, open,respectivel y, into the water-chambers C C', and are made long enough to allow ofthe proper movements of the forked projections H H', which extend downward, respectively, from the valves and through such ports d d. Each of these forked projections embraces one of-twc eccentrics, I I, fixed upon a cranked shaft, K, which goes transversely through the case,and is provided with two bell-cranks, g g', which are so arranged that one may stand at an angle of ninety degrees with respect to the other.. From the wrists of the said cranks two connecting-rods, h, extend, respectively, to two pistons, L L', which are disposed in the two cylinders-one piston to each of them-as shown in Fig. 2 of the drawings. Each valve is to be provided with a straight guide-tongue, c', xed in its upper side and made to enter a grooved bar, k, which extends into a socket, ,Vformed in the top of the case. Screws m m, going through the said top, press upon the groo'ved bar and Serve to maintain the valve in proper Contact with its seat` as either may wear.

Leading into the valve-chest B there is an opening, n, for the introduction of water thereto under head or pressure.

The two eccentrics I I' are so arranged that their greatestv eccentricitics may be nearly ninety degrees distant.

The red lines in Fig. 4 represent the positionl of one valve and its eccentric with reference to the other and its eccentric, which are indicated in black lines.

In order either to readily put the cranked 'shaft in place within or to remove it from the waterchambers C C', it is inserted in two stuffing-boxes, N 0, each of which has a concentric tenon, o, which enters a corresponding opening or passage, p, made through the side of the case. Vhere the shaft K goes through the partition c, such partition is provided with a rectangular opening, p', which extends to the end q of the case,and is provided with two slides, r s, vwhich slide longitudinally into the opening and are arranged to fill it, and so that one of them shall be in rear and the other in front of the shaft. They` are chambered around the shaft and contain packing t,which, extending about the shaft, makes a close joint around it. The tenon-opening of the sides of the case being of sufficient size, their. stuffingboxes and the slide r will readily admit ofthe shaft being either removed from the case or put in place therein, as circumstances may require, when the end q is oit' the case.

In the operation of the above-described i water-meter there is a continuous rotary movement of the shaft, which is particularly favorable for the application of an indicating apparatus, by which the number of movements of the pistons may be registered or denoted.

By the peculiar arrangement of the cranks and eccentrics the crank of each piston While at its dead-point will be helped over the same by the pressure of the other piston on its own crank. The Water which maybe entering one chamber on one side of a piston Will put the piston in motion and produce expulsion ofthe Water from the chamber on the opposite side of the piston, such Water being driven into and through the education-pipe.

The arrangement of the valves, valve-chest, waterchambers,v cylinders, pistons, crankshaft, cranks, eccentrics, valve forks, and eduction-pipe is one which is peculiarly advantageous for producing an effective watermeasuring` apparatus, one little liable to get out of order or be obstructed in its operations.

am aware that two pistons and cylinders with a valve apparatus are common to many Water-meters. Therefore I do not claim them as so used; but

What do claim is- 1. The above-described arrangement of the eduction-passage, valve chest, Water chambers, cylinders, pistons, Valves, and valveoperating mechanism,as applied in manner and so as to operate together substantially as set forth.

2. The tenoned stuing boxes and the slides applied to the case and its partition, and the shaft K, substantially in manner and for the purpose as specified. JOHN S. BARDEN.
